Hey ya'll, so for the last few weeks, I've been working on another PIC based synth project that I'm excited about and I thought I would share it with the board.

The hardware consists of a 16F685 chip, a quad op-amp, 2 PC mounted pots, some resistor arrays and some diodes all fit on a 50mm x 50mm PCB. This gives two 4-bit, AC coupled outputs for audio, 4 switch inputs, 2 inputs for triggers/gates and 2 cv inputs. With this I've written three different pieces of software:

1.Dual Decaying Noise. 2 digital noise outputs, the knobs set the decay, and the switches select between linear and logarithmic decay curves and whether decay begins at the rising or falling edge of the input trigger/gate.

2.Dual Delaying Noise. 2 digital noise outputs, but with software emulation of a delay effect. The knobs set the Decay time, Delay time, number of repeats and Delay level for each channel.

3.Decaying Noise/Tones. Each output is switchable between noise and square wave. The knobs control decay times and frequencies. This lets you have a kick and a snare sound from the same module.
